ciliaries spotted black and white; the northern form strut hivmcuhcs 

 (northeast and east Africa ; from the Harrar and Hawash districts of 

 Ethiopia, and the Danakil coast of Eritrea, soutli to central Tan- 

 ganyika Territory) has the lores and superciliaries pure white with 

 no black spots. 



In the same publication Neumann described a new species, 

 adolp'-fnederici, said to differ from kori in having a large black 

 patch with whitish streaks running lengthwise through it on the 

 throat; the basal half of these feathers being pure white without 

 barrings. This species according to Sclater --^ is known only from the 

 type, a head and neck, and is considered a doubtful species. It is in 

 reality even less than that, nothing but an occasional melanism that 

 crops out once in a while througliout the range of struthiunculus. 

 The bird collected at the Hawash Eiver is exactly like the descrip- 

 tion of adolfi-fHederici and so is a specimen in Museum of Compara- 

 tive Zoology (No. 56341) from the plains north of Nyeri. Kenya 

 Colon3^ These three (the type from Mara River, east coast of Lake 

 Victoria, and the two just mentioned) indicate that adolfi-friederici 

 appears here and there together with stnithiunculus, throughout the 

 range of the latter, with which it is undoubtedly identical. The 

 barring on the neck is slightly heavier, the white bars relatively 

 wider in these birds than in typical stnithiunculus^ but some speci- 

 mens of the latter have this character as in the so-called adotfi- 

 friedericL 



The range of struthiunculus is more extensive than indicated by 

 Sclater,-^ who writes it as " Southern Abyssinia south to Kenya 

 Colony and Somaliland." Neumann -- gives it as south to middle 

 Tanganyika Territory, in the coastal districts only. Recently, it has 

 been found to occur inland as well in Tanganyika Territory. Thus, 

 Schuster-* saw it at Singida and near Shinyanga (northeastern 

 Unyamwezi district), and Loveridge collected a specimen (now in 

 the Museum of Comparative Zoology) at Sagayo, Mwanza, and saw 

 another at Mlewa's (15 miles north of Singida). 



Older birds have the lesser upper wing coverts more grayish, less 

 brownish than younger adults, and have the whitish markings on 

 the inner webs of the primaries more restricted in the outer remiges. 

 The outermost primary is usually not marked or mottled with white; 

 in large adults the next one is almost entirely unmarked, except a 

 little on the basal part of the inner web, while in smaller adults this 

 feather is delinitely but incompletely banded with white on the 

 proximal three-fifths of the inner web.
